Rather than being called Demerjian, the smaller one is called Nabaztag but just like Charlie it can wiggle its ears and sing songs as well as read out emails.
According to the People's Daily Nabaztag can also alert you to a stock collapse and give you information about traffic jams. And so can the Demerjian, nah nah.
Nabaztag is 23 centimetres high, so it's much shorter than Demerjian. µ
